Selling a car wash at a glance
Step-by-step: selling a car wash
- Get a realistic range first
Run the car wash valuation calculator and recast your earnings to SDE with the SDE calculator. Know the number before a buyer names one.
- Fix what buyers discount
Owner dependence, customer concentration and messy books cost the most. Most can be improved in 6-24 months.
- Sort out licenses and transferability
List every license, permit, registration and contract and who holds it. The table below shows the ones that trip up car wash sales.
- Assemble the documents
Buyers and lenders will ask for the items in the checklist below; having them ready shortens diligence.
- Decide how to find buyers
Broker, M&A adviser, direct outreach, or responding to an approach you already have. See broker vs DIY.
- Compare offers on terms, not just price
Cash at close, seller notes, earn-outs, rollover equity, escrow and your post-sale role. See letters of intent.
- Diligence and purchase agreement
Expect financial (sometimes a quality of earnings review), legal and licensing diligence, then the purchase agreement.
- Close and transition
Licenses, payer or carrier contracts, leases and customer notices move on the closing timeline; plan your transition role in writing.
